right now I fear the only sane answer is "set all to permissive
behavior"; the minimum for fc5 would be everything that can do plugins
of any kind, or uses libraries that tend to get replaced (3D ones ;).
But that ends up being a whole whopping lot...

I really wish the user notification/config thing existed, but that will
take time to get right for sure...
